[Feature Request] Give option to use local GlitchTip instead of Sentry

[dekoza]

GlitchTip is an open-source Sentry alternative. It can be run on the same docker stack as the rest of services. It even uses the same API so using it is just a matter of adding its image to docker-compose and providing DSN.

The exact same thing could be said for Bugsink.

On the flip-side of that: since it's "just a DSN", might as well simply let people put in that DSN instead.
